Export a UMG as TikZ code

Generates a tikzpicture in the dialect of the umg-style.tex lexicon distributed with the package (see system.file("tikz", "umg-style.tex", package = "umg")), so that programmatic diagrams are stylistically identical to hand-written ones. The output compiles inside any document whose preamble loads TikZ and inputs umg-style.tex.

Usage

umg_to_tikz(model, file = NULL, digits = 2)

Arguments

model

An object of class umg; layout is computed if absent.

file

Optional path; when supplied the code is written there.

digits

Coordinate rounding (default 2).

Value

The TikZ code as a character vector, invisibly when file is supplied.
